MANIFOLDING ATTACHMENT FOR TYPEWRITERS.

pplication filed'Decemlier 12, 1921.A Serial No. 521,666.

To all 'whom t meenam: Y

Be it known that I, 'MALCOLM L. Cossrr'r, a citizen of the United States, residing at Alameda, in the county of Alameda and State ofl California., have invented certain new and' useful 'Improvements in Manifolding Attachments for Typewriters, of which the following is a specification.

My invention relates to Vmanifolding atv tachments for t pewriters, comprising one or more manifollling members, with means carried by the platen-carriage of themachine, for moving said members into and out off functional position in the line of typeim act.

ne of the objects of my present invention is to provide for moving the manifolding member to and from functional position in an arcuate path parallel with the axis of the platen, so that when out of use said member-is in a vertical position at one end of the platen. Y

Another object is to adapt the movement above noted for use in conjunction with a second movement of the manifolding member in an arcuate path perpendicular to said first named movement. Another object is to rovidey a simple, cheap and eii'ective vguide-member for directing the manifolding member outwardly from a chambered platen in which 'it is housed and from which it is Jadapted to be drawn for presentment .in`

functional position. l

With these objects in view, my invention consists in the -novel manifolding attachment for typewriters which I shall now fully describe, by reference to the .accompanying drawings, in which- Fig. 1 is an end elevation of my manifold# AFig. 4 is a longitudinal section of the chambered lend of the platen, on the line v4.--4 of Fig. 1, showing the manifolding members housed therein.

Fig. 5 is a section on the line of.

rotation upon the platen shaft 3.

ing lug at the free end of the manifoldin Fig. 11 is a view showing the manifolding ribbon carriers adapted for arcuate movement only in a plane parallel with the platen axis.

1 indicates the platen carriage of a typewriter and 2 the platen, having a shaft 3. for turning it for line-spacing, as usual.

The platen 2 has at one enda chamber 4, as seen in Figs. 4 and, in which is housed a spool 5, mounted for indeperijdent on this spool is wound a manifolding memlber 6 of suitable nature and shape, say, for example, in the form of a ribbon. rlhere may be a plurality of these spools and ribbons, here shown as two.

lUpon a fixed bar 7 of the platen carriage is secured a bracket 8, Figs. 1 and 2, which is secured as by means of screws 9, Figs. 1 and 4, to the head of a sleeve 10 within the chamber of the platen. To this sleeve is secured a skeleton guide member 11, having inclined direction Abars 11', over which the ribbons pass from the spools 5, as seen in Fig. 6. rThis guide member is made of wire and its angular direction bars 11 are atdiflerent levels to adapt them to severally receive and guide the two manifolding ribbons in noninterfering parallel planes, out jfrom the platen end throu h an aperture 10' in the head of the sieve 10, as shown in Fig. 4.

12 is a carrying arm, pivoted at 12 to the fixed bracket 8, and adapted to move in an arcuate path in aplane transverse to the platen axis. The free end of this arm is provided with spaced-guides 13, 4, one or each ribbon, the forward edgesfof said guides having impaling teethFig. 1. To

the upper portion of the free end of said arm 12 are hinged by means of the cross pintles 14,-Fig: 8, dtwo rods 15 which extend, as shown 1n Figs. 2 and 3, parallel with the platen. The free end of each rod` is provided with a toothed guide lug 16, such as is shown in Fig. 7.

The operation of the attachment is as follows In Ythe relatively permanent nonfunctional position, the arm 12 and its rods ends of the rods 15. The ribbons are temporarilyimpaledupon the teeth of the guides whereby they are releasably held under proper tension. When the ribbons are need.- ed for making carbon copies, the arm 12 is brought down through an arcuate path, about its pivotal center at 12',` bothrods 15 and ribbons 6 accompanying it, until the ribbons reach their functional/4 position in front of the platen in the lineof type impact.

A reversal of this movement carries them out of use.

But if the non-usey of the ribbons is to be relatively temporary,or for any other reason it be found not desirable to throw them up bythe movement of the arm 12 as above described, they or either of themmay be turned out of use by taking hold of the free end of the rods 15 .and turningsaid rods about their pivot pintles 14, so that said rods and ribbons rise 1n an arc in a vertical plane parallel with the platen, until they stand upright at one end of the laten, as is indicated by the dotted lines in igs. 1 and 3; and from this position'they may be turned down again for use. In order to hold the parts at the limits of this movement, the pivot pintles 14 of the rod hinges are releasably locked by suitable means, was, for

example, by the notches 17 and spring pressed balls 18, shown in Figs. 9 and 10.

'Thus the ribbons may be thrown into and out of use by arcuate movements in planes perpendicular. to each other. In practice the first movement, that is .to say, with the arm 12, may be employed for a more permanent disuse fof the ribbons, while the last movement, namely that with the rods 15, is

,. convenient for temporary purposes: When the portion orv section of the lmanifoldi ribbon stretched betweenthe guides 14 an 16 is used up, it is released from the impaling teeth of said guides and a fresh portion is drawn out from the spool housed in the platen, until it 'lies between said guides and is then again impaled thereon, the used section or portion being cut or torn of. In this successive drawing .out of fresh portions,

the skeleton guide-member 1 1 within the chambered platen effectively directs the course of the ribbon, while'in the case of plural. ribbons, said member keeps 'them apart so that they do not'interfere with each other. In Fig. l1, I'show a modification in which the carrying arm 12 and bracket 8 are integral, so that said arm has no arcuate movement butis permanently horizontal. The arm, however, carries the two hinged rods 15 as before, and in this case, the ribbons have only a single arcuate movement in a vertical plane parallel with the platen. i The dotted lines show the elevated position 8o of said rods. Although, as stated hereinbefore, the ribbons carried by and between the end of the arm 12 and the ends of the rods 15 are held under tension by being releasably impaled, said ribbons, under the blows of the type tend to slacken during use. This is overcome by making the rods 15 slightly resilient or springy Ain their length. In initially impaling the ribbon on the lug 16 at the free end of the rod, said rod is sllghtly. iexed, and is so held by the impaled ribbon. Then as the ribbon tends to slacken from use, the re siliency of the rod automatically takes vup the slack, so that, in addition to the initial tension due to impaling it on the toothed members, there is the automatic constant tension strain due to the flexed resilient rod.

I claim 1; A manifolding attachment for type- 10o writers comprising a. manifolding member; and a rod by which said member is carried, said rod beingv associated with the platencarriagevof the machine by al hinge-connection at one end adapting it to move said 105 member in an arcuate path parallel with the platenaxis from vertical position at one end of the machine platen to a horizontal position in the line of type impact, and back again.

2. A .manifolding attachment for typewriters comprising a manifolding member;

. an armassociated withthe platen carriage of the machine at one end of and transverse to the platen; a rod carried by the arm and y11,15
